2-dimensional visualization of the context vectors of war, crime, and terror.

The distance between points in the visualized space represents the semantic distance between the points. That is, the further apart two regions of space are the more dissimilar they are. Overlap represents an overlap in the contexts of use for the two terms. These figures were extracted from Movie S1. The left frame is for June of 2000, and the right is for June of 2004. The data used in each frame is based on the 12 months starting with the indicated month. Because of memory constraints, context vectors for the 3 terms were aggregated by speaker for each month. This aggregated set of vectors was then used as a whole to compute the MDS, and plotted as a yearly running average on a month-by-month basis.
